LENA: A low-energy neutrino observatory and proton decay detector — •Jürgen Winter, Franz von Feilitzsch, Marianne Göger-Neff, Teresa Marrodán Undagoitia, Lothar Oberauer, Walter Potzel, and Michael Wurm — Physik-Department E15, Technische Universität München, James-Franck-Straße, 85748 Garching

The proposed project LENA (Low Energy Neutrino Astronomy) comprises a 50 kt liquid-scintillator multipurpose detector. Thanks to a low energy threshold, high energy resolution, and a large detector volume, LENA could offer the possibility to answer numerous physics questions. The goals of LENA extend to the fields of astrophysics (e.g. the observation of supernova, diffuse supernova and solar neutrinos), particle physics (search for proton decay), and geophysics (geoneutrinos). An overview of the potential of LENA is given in this talk, along with an introduction to scintillator physics and detector simulation.

LENA is a part of the European LAGUNA (Large Apparatus for Grand Unification and Neutrino Physics) collaboration that has been founded in order to study the feasibility of large-scale detectors with a common physics program. Apart from the liquid-scintillator detector LENA, it involves a 0.5 Mt water Cherenkov detector (MEMPHYS) and a 100 kt liquid Argon time projection chamber (GLACIER).
